The ribonucleic acid (RNA) is a single-stranded molecule composed of a long chain of consecutive nucleotides.
In RNA, there are four types of nucleotides, each containing one different nitrogenous base, i.e., Adenine, Uracil, Guanine and Cytosine.
In RNA, Uracil nitrogenous bases replace Thymine bases observed in the DNA molecule.
